ESP32 ESP-32S 30P NodeMCU Development Board Wireless WiFi

ESP32 ESP-32S 30P NodeMCU Development Board is a powerful, low-power system-on-chip (SoC) module featuring integrated Wi-Fi and dual-mode Bluetooth (Classic and BLE). Based on the ESP-WROOM-32 module with a 30-pin DIP layout, it is engineered for advanced IoT applications, smart home automation, wireless sensor networks, and high-performance robotics. Driven by a dual-core 32-bit Xtensa Tensilica LX6 microprocessor operating at up to 240 MHz, it offers exceptional processing power, rich peripheral interfaces, and ultra-low power consumption for student, academic, and industrial prototyping.

Features

• Powered by the dual-core 32-bit Xtensa LX6 microprocessor running up to 240 MHz
• Integrated 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth v4.2 BR/EDR + BLE (Bluetooth Low Energy)
• Standard 30-pin breadboard-friendly layout with dual inline headers
• Onboard CP2102 or CH340 USB-to-UART converter for seamless programming and debugging
• Onboard 3.3V voltage regulator supporting USB 5V or external power inputs
• Rich peripheral connectivity: capacitive touch, Hall sensor, ADC, DAC, UART, SPI, I2C, PWM, and I2S
• Low-power co-processor for deep-sleep energy monitoring
• Supports Station (STA), Access Point (AP), and hybrid STA+AP Wi-Fi modes
• Fully compatible with Arduino IDE, ESP-IDF, MicroPython, and FreeRTOS environments
• Supports Over-The-Air (OTA) firmware updates over Wi-Fi

Applications

• Smart home automation systems controlling multi-channel relays, sensors, and voice interfaces via BLE/Wi-Fi
• Industrial IoT telemetry, cloud connectivity, and MQTT/HTTP web servers
• Computer vision, camera streaming (ESP32-CAM pairing), and real-time audio signal processing
• Advanced robotics, wireless RC vehicles, drone controllers, and BLE mesh network systems
• Microcontroller-based university thesis, polytechnic diploma, and engineering research projects
• Battery-powered remote environmental and agricultural monitoring systems utilizing deep-sleep modes

Important Notes:

• The ESP32 GPIO logic operates strictly at 3.3V; connecting 5V signals directly to any pin will permanently damage the chip.
• Install the CP2102 or CH340 USB driver on your computer if the board is not detected by the Arduino IDE upon connection.
• When uploading code via the Arduino IDE, press and hold the "BOOT" button on the board when "Connecting..." appears in the serial console if auto-flash fails.
• Pins GPIO 34, 35, 36 (VP), and 39 (VN) are input-only pins and do not feature internal pull-up/pull-down resistors or PWM capability.
• Ensure a stable 5V power supply (at least 500mA) during active Wi-Fi and Bluetooth transmission bursts to prevent brownout resets.
• Establish a common GND connection between the ESP32 and all external modules, drivers, and sensors.

Package includes

• 1 x ESP32 ESP-32S 30P NodeMCU Development Board
